Now when the ancl'connected to; enfangnla'r bracket. 6, the picker stick l movestowartl the left, it'will I zontal position.

strike the stops 18 on the upper left-hand bolt 16 and it will then pull along the parts 14, 15 and. .17 against the tension of the spring 21, until the latter passes to the opposite side of a central vertical line, that is, passes over dead center. After this, the spring will tend to rapidly move the parts toward the left until the rocker arms have moved the parts 15 and. 17 to the dotted line position shown in Fig. 1, at which time the bar 15 will come to rest gently against the surface 25 and the picker stick will be halted and prevented from rebounding.

This movement has thrown the shuttle 2 over the lay toward the left end of the latter, and subsequently the picker stick on the opposite end of the lay throws the shuttle back. The shuttle in returning to its original position will strike the picker stick and the picker stick will move freely until it strikes the stops at the right end of the bars 15 and 17, and then the parts will move toward the right retarded by the spring 21, until the latter passes dead. center, after which it will. function to speedily move the parts into the full'line position in Fig. 1. Any rebound of the check or picker stick will then be prevented by the overbalanced bar '15, and the particular rocker arm 14-, which at this time is in a substantially horiln actual practice the strap 5, which is about 8 inches wide and inch thick, is rigidly secured to the loom by the bolt 8,

and the parts 10 and Y12 are rigidly at-' tached to this strap, while the other parts are mounted for relatively free movement. Furthermore, the front retaining rod 17 and the strap 23 act as guards for the spring 21 an d prevent the picker stick from contacting with said spring.

From the foregoing it is believed that the construction, operation and advantages of the invention may be readily understood, and I am aware that changes may be made in the details disclosed without departing from the spirit of the invention as expressed in the claims.

What I claim and desire to secure by Let ters Patent is:

1. A picker stick check for looms including a retaining frame provided with stops between which a picker stick is adapted to oscillate, a plurality of swinging arms carrying said frame, and. spring means connected to the frame and adapted to retard the movement of the frame for a portion of its travel and to assist in its movement during the remainder of its travel.

2. A picker stick check for looms including a checking member provided with stops faced with leather or like resilient material. betweenwhich a picker stick is adapted to reciprocate, supporting means for the checking member and spring means adapted to .ing another portion retardthe movement of the checking member during a portion of its travel and to as sist in the movement during another portion of its travel.

3. In a picker stick check for looms, a retaining frame adapted to be reciprocated by a picker stick, and means associated with said retainii'ig frame for retarding the move ment of the latter during a portion of its travel and to assist in its movement during another-portion of its travel.

4. A picker stick check for looms comprising a supporting member, a bar carried by the supporting member, rocker arms carried by the bar, aretaining frame carried by the rocker arms, and spring means connected to the retaining frame and thebar for'retarding the movement of said frame during a portion of its travel and to assist in its movement during another travel. 1 v

5. A picker stick check for looms including a supporting member, a bar carried by said member, a retaining frame pivotally spaced. from said bar by a plurality of rocker arms, said retaining frame being adapted to be reciprocated by a pickerstick, and spring means associated with the retaining frame and adapted to retard its movement during a portion of itstravel and to assist in its movement during another portion of its travel,

6. A picker stick check for looms comprising a hanger strap provided at one end with an angular bracket adapted'to be rigidlysecured to a loom, a supporting bar arranged at the other end of said strap, a retaining frame, rocker arms pivotally connected between the supporting bar and the retaining frame, said retaining frame being adapted to be reciproeated by a picker stick, and

portion of its means for retarding thenmovement of the 7 last mentioned member during a portion of its travel and to assist in its movement d ur of its travel.

7. A picker stick check for looms including a hanger strap, a supporting bar carried by the strap, rocker arms pivotally connected to said bar, a retaining frame carriedby the rocker arms and adapted to be reciprocated by a picker stick, and spring means toretard the movement of the retaining frame during a portion of its travel and to assist in such movement during another portion of its travel in the same direction.

. 8. A picker stick check for looms compris ing a hanger strap, a supporting bar carried by the strap, rocker arms pivotally coning a supporting structure, rocker arms having certain of their ends pivotally connected to the supporting structure, a retaining frame pivotally connected to the other ends of the rocker arms, and a spring connecting said frame to the supporting structure and adapted to retard the movementof the frame during a portion of its travel in one direction and to assist in moving said frame during another portion of its travel in the same direction. 7

10. A picker stickcheck for looms comprising a supporting structure a stop block carried by the supporting structure and'having oppositely inclined faces, rocker arms pivotally connected to the supporting structare, a retaining frame pivotally connected ranged ture. I

portions of the retaining frame and the sup- 7 porting structure.

11. A picker stick check for looms as claimed in claim 10 including stops arin the ends of the retaining frame and adapted to be struck by a picker stick.

to the rocker arms and adapted to be moved 12. A picker stick check as claimed in a claim 10 including guards connected to the supporting structure and prevent the picker stick from contacting 1 with said spring.
